Fundamentals
Why State Law Matters
Simple explanation
State law governs many execution, probate, marital-property, spousal-rights, trust, creditor, and health-decision rules, while federal law overlays transfer, income, retirement, and benefit questions.
- Different connections can point to different states
- Residence, domicile, property location, trust situs, and business formation can point to different laws.
- A move can change administration and tax
- A document validly signed elsewhere may still work, but administration and tax questions can change after a move.
- State flags start research; they do not end it
- State flags in The Estate Guide are research starting points, not conclusions.
The four parts of a working plan
- People Identify the owner, decision-makers, fiduciaries, and beneficiaries.
- Property Map title, contract rights, debts, tax attributes, and practical access.
- Documents Coordinate wills, trusts, powers, directives, and beneficiary forms.
- Review Revisit the plan after life, ownership, law, tax, or relationship changes.
Go deeper
State law decides most of how a plan works, from signing a will to paying a state death tax. This guide explains why domicile, property location and trust situs can each point to a different state.
Who typically explores it
People who have moved to a new state, owners of homes or land in more than one state, and families with a trust administered somewhere else.
Tax lens
State tax systems run separately from federal law: some states tax estates, some tax inheritances, and Maryland taxes both. Domicile at death usually decides which state taxes intangible property such as investments, while real estate is taxed where it sits.
Common mistakes
Using residence and domicile interchangeably
Choosing trust situs from a ranking alone
