LPA for Couples: Should You Create Mirror LPAs?
Most couples create matching LPAs naming each other as attorney — but there are pitfalls to avoid.
Written by Anthony Dalton · Reviewed by James Tyrrell · Last reviewed
When couples sit down to sort out their Lasting Powers of Attorney, the most natural instinct is to create matching arrangements — each partner naming the other as their primary attorney, with the same replacements, the same structure, the same preferences. This approach is known as creating "mirror LPAs," and it is by far the most common choice for married couples and long-term partners in England and Wales. But is it always the right approach, and what should you watch out for?
At a glance
- Mirror LPAs are matching documents where each partner names the other as their primary attorney
- Each LPA is a completely independent legal document — one does not affect the other
- You must always name replacement attorneys, in case both partners lose capacity
- The OPG registration fee is £92 per LPA — four LPAs for a couple costs £368 in government fees
What Are Mirror LPAs?
Mirror LPAs are two separate Lasting Powers of Attorney that follow the same structure. Each partner creates their own LPA, naming the other as their primary attorney. Both LPAs typically appoint the same replacement attorneys, use the same decision-making structure (joint and several, for example), and include similar preferences and instructions.
The word "mirror" is not a legal term — you will not find it in the Mental Capacity Act 2005. It is simply a practical description. Each LPA is still a completely independent legal document, registered separately with the Office of the Public Guardian. One does not depend on the other in any legal sense.
Take David and Rachel, for example. David creates a Property and Financial Affairs LPA naming Rachel as his attorney, with their son Tom as replacement. Rachel creates an identical LPA naming David as her attorney, also with Tom as replacement. They then do the same for their Health and Welfare LPAs. Four LPAs in total, mirroring each other perfectly.
Why Most Couples Choose to Mirror Their LPAs
For most couples, mirroring makes complete sense. Your partner already knows your finances, understands your health preferences, and is the person you trust most. There are several practical reasons why this approach is so popular:
- Trust and familiarity — your partner typically knows you better than anyone else and understands how you would want decisions made
- Simplicity — matching structures are easier to set up, explain to family, and manage in practice
- Fairness — both partners have equal protection, rather than only one person being covered
- Cost efficiency — creating all LPAs at the same time saves on professional fees and reduces duplication of effort
- Consistency — if both partners lose capacity, the same replacement attorneys step in for both, avoiding confusion

How Mirror LPAs Work in Practice
Most couples who create mirror LPAs end up with four documents in total. Each person creates:
Property & Financial Affairs LPA
Covers bank accounts, pensions, investments, property, bills and all financial matters. Can be used while you still have capacity if you choose.
Health & Welfare LPA
Covers medical treatment, care arrangements, daily routine, and — if you choose — decisions about life-sustaining treatment. Only used once you lack capacity.
Each LPA names the other partner as primary attorney, with agreed replacement attorneys (usually adult children, siblings, or close friends). The couple typically chooses the same decision-making structure for both — most commonly joint and several, which gives flexibility if one attorney is unavailable.
For a fuller explanation of why both types are recommended, see our guide on whether you should create both types of LPA.
The Critical Question: What If Both Partners Lose Capacity?
This is the single biggest risk with mirror LPAs, and it catches more couples out than you might expect. If each partner names the other as their sole attorney with no replacements, and both partners lose mental capacity, neither LPA will function. There is no available attorney for either person.
What catches people out is that this does not just apply to rare catastrophic events. Dementia, for instance, can develop gradually in both partners over a similar timeframe. One partner may already be acting as attorney for the other when their own capacity begins to decline. Without replacement attorneys in place, the family is left with no one authorised to act for either parent.
Key point: If you are creating mirror LPAs, you must name replacement attorneys. Without them, both LPAs become useless if both partners lose capacity — and your family would need to apply to the Court of Protection for deputyship, costing £1,000 or more and taking months.
The solution is straightforward: always appoint at least one replacement attorney in each LPA. Adult children are the most common choice. Some couples also appoint their children as joint attorneys alongside the spouse from the outset, so they are already authorised to act if the primary attorney cannot.
When Mirror LPAs May Not Be the Right Choice
Mirroring works well for most couples, but there are situations where a different approach may be more appropriate:
- Second marriages or blended families — if each partner has children from a previous relationship, you may want different replacement attorneys to reflect each side of the family
- Significant age gap — if one partner is considerably older, it may not be realistic to name the younger partner as their sole attorney long-term without additional replacements
- Different financial situations — if one partner has a business, significant personal assets, or complex financial arrangements, they may need a different attorney structure (perhaps a professional attorney or a trusted business partner)
- Strained family relationships — if one partner’s children do not get along with the other partner, naming the stepparent as attorney could create conflict
- One partner has specific health needs — different care preferences or medical conditions may require different Health and Welfare arrangements
In these cases, each partner should still create their own LPAs — but the structures do not need to match. You might name your spouse as primary attorney for one type of LPA but choose a different arrangement for the other. There is no rule that says both partners must have identical documents.

Cost Savings When Creating LPAs Together as a Couple
The OPG registration fee is £92 per LPA. For a couple creating both types each, that is four LPAs at a total of £368 in government fees. There is no couples discount on the registration fee itself — each LPA is charged individually.
Where the real savings come in is on professional or service fees. A solicitor might charge £300–£1,000 per LPA, which could mean £1,200–£4,000 for four LPAs. Online LPA services typically charge far less, and many offer specific couples packages or discounts when both partners create their LPAs at the same time.
Worth knowing: if either partner receives means-tested benefits or earns less than £12,000 per year, they may qualify for a fee exemption or 50% reduction on the registration fee. Eligibility is assessed per person, so one partner could pay the full fee while the other qualifies for a reduction. For more detail, see our guide on how much an LPA costs.
Practical Tips for Creating Mirror LPAs
If you and your partner have decided to create mirror LPAs, these practical tips will help the process go smoothly:
Create both sets at the same time
Doing everything together means you only need to gather information once, discuss your choices once, and coordinate signing once. It also avoids the common trap where one partner sorts theirs out and the other never gets around to it.
Use the same certificate provider
Both partners can use the same person as their certificate provider, as long as that person is independent of the attorneys. A family friend or your GP who knows both of you is ideal. Your spouse cannot be your certificate provider if they are named as your attorney.
Sign on the same day if possible
While there is no legal requirement to sign at the same time, it is far more convenient. You can gather the certificate provider and witnesses for one session rather than organising two separate signing events.
Agree on replacement attorneys together
Discuss who should step in if either of you cannot act. Choosing the same replacements keeps things consistent and avoids confusion for your family down the line.
Register all LPAs at the same time
You can send all four LPAs to the OPG together. This keeps the process simple and means they should all come back around the same time — typically within 8 to 10 weeks if there are no mistakes.
Each LPA Is Independent — One Does Not Affect the Other
A common misunderstanding is that mirror LPAs are somehow legally linked. They are not. Each LPA is a standalone document, created by one donor and registered independently. This means:
- If one partner revokes their LPA, the other partner’s LPA remains completely valid
- If one partner dies, the surviving partner’s LPA continues to function (though the deceased partner can no longer act as attorney — the replacement steps in)
- If one partner’s LPA is rejected by the OPG for an error, the other partner’s is unaffected
- Changes to one LPA do not require changes to the other
Key point: If your partner dies or loses capacity and was named as your attorney, your replacement attorney will automatically step in. This is exactly why replacement attorneys are so important for couples — your LPA continues to work even when your primary attorney can no longer act.
That said, if one partner revokes their LPA and creates a new one with different attorneys, it is worth reviewing whether the other partner’s LPA still reflects their wishes. Life changes — divorce, bereavement, family disagreements — may mean both LPAs need updating, even if there is no legal obligation to do so.

Key Takeaways
- Replacement attorneys are essential — if both partners lose capacity and neither named a replacement, both LPAs become useless and the family faces Court of Protection deputyship
- Mirror LPAs are not legally linked — revoking one does not affect the other, and each is registered independently with the OPG
- Blended families may need different structures — second marriages, significant age gaps, or complex finances may mean matching LPAs are not the right choice
- Create both sets at the same time — this avoids the common trap where one partner sorts theirs out and the other never gets around to it
Common Questions About Mirror LPAs for Couples
Do couples have to create mirror LPAs?
No. Mirror LPAs are common but not compulsory. Each person creates their own LPA independently. You can choose different attorneys, different structures, and different preferences. Mirroring is simply the most popular approach for couples who want matching arrangements.
What happens if one partner revokes their mirror LPA?
Nothing happens to the other partner’s LPA. Each LPA is a completely independent legal document. If one partner revokes theirs, the other’s remains fully valid and registered. However, the partner who revoked will need to create a new LPA if they still want protection.
How much do mirror LPAs cost for a couple?
The OPG registration fee is £92 per LPA. If both partners create both types of LPA (Property & Financial and Health & Welfare), that is four LPAs at £368 in registration fees. Many online services offer couples discounts on their service fees, which can reduce the overall cost significantly compared to using a solicitor.
Can both partners use the same certificate provider?
Yes. Both partners can use the same person as their certificate provider, provided that person is independent of the attorneys named in each LPA. A family friend, neighbour, or GP who knows both partners well is a common choice. Your spouse cannot be your certificate provider if they are named as your attorney.
