Selling a parent’s property involves a different set of legal requirements depending on the parent’s circumstances. The starting point is establishing what legal authority exists to act on the parent’s behalf, or whether the estate is being administered following their death.

Situation 1: Parent is alive and has capacity
If a parent is alive and has mental capacity, they are the legal owner and the only person who can authorise its sale. A child cannot sell a parent’s property by virtue of being a family member. The parent must sign all legal documents and provide informed consent throughout.
A Lasting Power of Attorney (LPA) for property and financial affairs, if registered, allows an attorney to act on the donor’s behalf in financial matters including property sales. This is useful when a parent needs assistance but remains legally capable of making decisions.
Situation 2: Parent is alive but has lost mental capacity
If a parent has lost mental capacity and did not make a registered LPA before doing so, the only route to managing their financial affairs is through the Court of Protection. The Court can appoint a deputy — a formal legal process taking several months. Until a deputyship order is granted, no sale can proceed.
Situation 3: Parent is alive but in long-term care
If the parent has capacity, the decision to sell is theirs. If they lack capacity, the process depends on whether an LPA or deputyship order is in place. Local authority means testing for care funding includes property assets unless a spouse or dependent is living there. Specialist financial advice is strongly recommended before selling a property in this context.
Situation 4: Parent has died
If a parent has died, the sale of their property is governed by probate. The executor named in the will — or the administrator appointed if there is no will — has authority to sell once the grant of probate or letters of administration have been issued. See the separate guides on probate for detailed guidance.
Using a cash buyer when selling a parent’s property
Cash buyers will purchase properties sold under LPA, deputyship, or probate. Where a parent is in care and the property is vacant, a cash sale may be attractive because it removes the ongoing cost of maintaining an empty property quickly. The price discount should be weighed against these costs.

Anyone selling under a power of attorney or as an executor has a legal duty to act in the parent’s or estate’s best interests. Decisions should be documented and, where the property is of significant value, taken with independent legal and financial advice.
