Quick answer

Yes, married couples should seriously consider lasting powers of attorney. Marriage gives you emotional closeness. It does not automatically give you legal authority to manage everything if your spouse loses mental capacity.

This catches families off guard.

Example: Sandra and Mike in Swansea

Picture Sandra and Mike in Swansea. They have been married for 38 years. Their house is joint, bills are shared, and Sandra knows every password because she runs the household. Mike then has a stroke. Suddenly Sandra needs to speak to his pension provider, deal with an ISA in his sole name, talk to the bank, and consider whether the house should be adapted or sold.

Everyone agrees Sandra is the right person. That does not mean every organisation can simply take her word for it.

A lasting power of attorney, or LPA, is the document that gives chosen people authority to act. There are two types.

The difference matters.

Your daughter might be able to help pay bills under a property and financial affairs LPA while you are physically unwell but mentally sharp, if you agree and the document allows it. But she cannot use a health and welfare LPA just because it is convenient. That only applies when you cannot make the relevant decision yourself.

Choosing attorneys without causing a family row

Begin with the practical question: who would need to act tomorrow if something happened? Your spouse may be obvious, but what if they are elderly too? What if they are in hospital with you after the same accident on the M4? What if your adult children disagree?

Next, think about how attorneys should act:

• jointly, meaning everyone must agree;

• jointly and severally, meaning any attorney can act;

• jointly for some decisions and separately for others.

Joint appointments can feel fair, but they may be awkward if one child lives in Manchester, one in London and urgent bank paperwork needs signing. Joint and several appointments are more flexible, but require trust.

LPAs should sit alongside your will, not underneath it. A will deals with death. An LPA deals with life. Many families have a beautiful will and no plan for the ten years before death, when dementia, stroke, frailty or serious illness may create the hardest decisions.

There are also limits. Attorneys cannot treat the donor's money like family money. GOV.UK guidance says property and financial affairs attorneys must keep the donor's finances separate and there are restrictions on gifts. Large gifts, interest-free loans or letting someone live rent-free in the donor's property may need Court of Protection approval.

That is another uncomfortable point. Sometimes the person who needs stopping is not a stranger. It is the well-meaning child who thinks, "Mum would have wanted me to have this now."

Before making LPAs, gather:

• full names and addresses for proposed attorneys;

• replacement attorney choices;

• views on life-sustaining treatment;

• any family conflict concerns;

• property and finance details;

• your will, if you have one.

The documents needed will vary. One spouse may mainly need authority to deal with a joint current account, pension provider, mortgage lender and utility companies. Another family may need attorneys to understand ISAs, rental income, private pensions and property records. Where there are operating businesses, private shares, trusts, investment managers, overseas accounts or GBP 10m-300m in investable assets, attorney choice should be coordinated with shareholder, trustee and adviser arrangements.

Caira can help you prepare a calm LPA planning note. Upload your draft LPA, will, family notes or questions from siblings, and ask Caira to summarise the practical choices in plain English. It can also help draft an email to your children explaining why you are appointing attorneys, before the conversation becomes urgent.

FAQ

Is it insulting to ask my spouse for an LPA?
No. An LPA is not about doubting your spouse. It is about giving banks, pension providers, doctors and other organisations a clear legal route to work with them.

Can my children just help if I give them my passwords?
Passwords are not legal authority. They may help with admin, but they do not give proper permission to manage accounts, sell property or make decisions.

Should I appoint all my children to keep things fair?
Maybe, but fairness and practicality are different. If every decision needs everyone, one absent or difficult attorney can slow urgent action.

Can attorneys give themselves money if Mum would have wanted it?
They must be careful. Attorneys must act for the donor, keep finances separate and take advice before making significant gifts or unusual arrangements.
