LPAs in blended families

Guidance from Estate Advisory Group

Written and legally reviewed by Ramani Gill TEP, Solicitor and private client practitioner·Last reviewed 13 August 2026

Second marriages plus adult children from a first is the situation the OPG sees most objections from.

Where the friction comes from

  • A new spouse controlling money the first family expects to inherit.
  • Stepchildren excluded from care decisions about a parent.
  • Sale of a family home occupied by the surviving spouse.
  • Suspicion about gifts and spending where records are not kept.

Structures that reduce it

ApproachEffect
Spouse plus one adult child, jointly and severallyTransparency without deadlock
Spouse for health, child for financesSeparates care from money
Joint for major decisions onlyBoth must agree on property sales
Professional attorney alongside familyNeutral hand on the money

The "jointly for some decisions, jointly and severally for others" option is powerful but easy to word badly — see jointly or jointly and severally.

Practical safeguards

  1. Name people to notify so nobody is surprised at registration.
  2. Ask attorneys to keep and share records.
  3. Write a letter of wishes about the family home.
  4. Review your will and LPA together so they tell the same story.

Common questions

Can a stepchild be an attorney?

Yes. There is no requirement to be a blood relative.

Can my children object to my spouse being attorney?

They can object to registration, but only on valid grounds such as fraud, pressure or the attorney being unsuitable. See objecting to an LPA registration.
