General will information, not signing instructions or legal advice. Check the current rules in the relevant state.

Capacity is decision- and time-specific; the relevant question is the legal standard for the act being taken at that time.

What the will can control

  • A diagnosis or advanced age alone does not answer whether a person can sign a particular will, trust, power, or contract.
  • A will generally directs probate property at death, nominates an executor, and can nominate guardians for minor children.
  • A will does not normally control property that passes by survivorship, beneficiary designation, trust ownership, or another contract-based transfer.

Execution and evidence file

  • dated medical and functional information relevant to the decision
  • drafting notes, witness observations, and prior consistent instructions
  • the signed original will and every codicil
  • a list of assets showing title and beneficiary designations

Coordination and backup choices

  • Which legal capacity standard applies to this document?
  • What accommodations would support the person's own decision-making?
  • Which assets would actually be controlled by the will?
  • What execution rules apply in the signing state?

Risks to pause on

  • Family members should not substitute their preferences for the person's own choices merely because help is needed.
  • Treating a draft, photocopy, or unsigned file as the operative original can create avoidable probate disputes.
