Many people assume that being someone’s “next of kin” automatically gives them the right to make decisions on that person’s behalf. In reality, the term “next of kin” has very limited legal significance in England and Wales. Whilst healthcare providers, care homes and other organisations may ask for details of a person’s next of kin, this does not, by itself, provide any legal authority to make decisions regarding that person’s finances, welfare, Lasting Powers of Attorney (LPAs), or Will.
The term “next of kin” generally refers to a person’s closest living relative. It may be a spouse, civil partner, child, sibling or another family member.
However, there is no single legal definition that automatically grants a next of kin decision-making powers. In most circumstances, being identified as next of kin simply means that you are the person who may be contacted in an emergency or kept informed about a loved one’s situation.
Only the attorneys formally appointed within a valid Lasting Power of Attorney (LPA) have the legal authority to act for the donor in managing their affairs. If a person loses mental capacity and no LPA is in place, their next of kin does not automatically step into that role. Instead, an application may need to be made to the Court of Protection for the appointment of a deputy. This process can be costly, time-consuming and significantly more restrictive than having an LPA in place.
The concept of next of kin is equally misunderstood in the context of Wills.
A next of kin has no authority to amend, revoke, interpret or control a person’s Will during their lifetime.
The individuals responsible for administering a deceased person’s estate are the executors named in the Will. Their authority arises from the Will itself, not from any familial relationship.
Where a person dies without leaving a valid Will, the intestacy rules determine who is entitled to inherit and who may apply to administer the estate. Whilst close relatives may benefit under these rules, this does not mean that the designation of next of kin carries legal authority in relation to the estate.
