Most of what an adult child needs to know about Maryland estate and incapacity planning concentrates in a few documents and two distinctive state-level taxes that together make Maryland one of the higher-friction estate environments in the US.

The four documents to have in place this year

1. Maryland Statutory Form Power of Attorney

Maryland adopted a statutory short-form Power of Attorney under Md. Estates & Trusts Code Ann. §17-202.1 Maryland banks and brokerages broadly accept the statutory form; non-statutory POAs are also valid but face more institutional scrutiny.

Key points:

2. Maryland Advance Directive

Maryland combines health-care POA and living will into a single Advance Directive under the Maryland Health Care Decisions Act (Md. Health-General §5-601 et seq.).2 The directive:

3. Last Will and Testament

Maryland wills are governed by Md. Estates & Trusts. The will must be signed by the testator and witnessed by two competent witnesses. Maryland recognizes self-proving affidavits, which streamline probate.

4. Revocable Living Trust

A revocable trust is often the right tool in Maryland for three reasons: probate avoidance (Orphans’ Court is more involved than informal probate in many states), estate- tax planning (Maryland’s $5M exemption is meaningfully below federal), and inheritance-tax planning (the trust can be structured to manage which beneficiaries fall inside vs outside the exempt class).

The Maryland estate tax

Maryland has a state estate tax with a $5M per-individual exemption. Unlike many other state estate taxes (and the federal exemption), Maryland’s exemption has not been adjusted in recent years, meaning rising asset values have pushed more Maryland families into the exposure zone. Maryland estate-tax rates are graduated, reaching up to 16% on amounts above the threshold.3

For estates between ~$5M and the federal exemption (~$13.99M for 2025), Maryland estate tax applies but federal does not. For estates above both thresholds, both apply.

The Maryland inheritance tax

Maryland is one of only six states with an inheritance tax, and one of only two (with New Jersey) imposing both inheritance and estate taxes. Maryland’s inheritance tax structure:4

Practical implications:

Probate in Maryland: the Orphans’ Court

Maryland uses specialized Orphans’ Courts — one in each of Maryland’s 24 jurisdictions — to oversee probate. The process:

Maryland personal representative commissions and attorney fees are statute-based with regulatory caps; the structure is somewhat formulaic and predictable.5 Even so, probate is more involved than in pure informal-probate states, which makes the revocable trust more common in Maryland than in some neighbors.

Out-of-state wills are generally valid in Maryland if valid where executed, but a Maryland review is wise:
