What this guide covers

  • Prevent partial intestacy with a residuary clause, ultimate taker, and deliberate anti-lapse/survivorship language.
  • Draft tax apportionment and marital/credit-shelter formulas to match intent — and re-test legacy formulas against the $15M exemption.
  • Define family terms and fiduciary succession precisely, and keep documents, designations, and titling internally consistent.

The full guide includes the detailed analysis, worked examples, statutory citations, and related resources below.
