Dementia stage determines what a family caregiver agreement must cover, how much it pays, and how often it needs to be rewritten. A document built for someone who still drives and manages medication looks nothing like one built for round-the-clock supervision. That gap matters because a caregiver agreement is a legal contract, not a handshake. Getting the timing and terms wrong can cost a family Medicaid eligibility later, or leave them unable to sign one at all.

Why Early Stage Is the Only Window to Sign
A personal care agreement — also called a caregiver contract or family care agreement — is a legally binding contract. That means the person with dementia who signs it must have legal capacity at the time of signing, according to a Caring.com attorney-nurse Q&A. Capacity is exactly what later-stage decline takes away.
MIT AgeLab's financial-planning caregiver guide notes that a power of attorney can only be granted while the principal still has legal capacity, and that someone in the mild stage of dementia may still understand information, make decisions, and communicate them. That makes the mild, or early, stage the practical window for signing both a power of attorney and a care agreement. The Alzheimer's Association's planning guidance recommends putting legal protections in place soon after diagnosis — a will, living trust, durable power of attorney for finances, and a healthcare directive — while the person can still understand and participate, according to its legal and financial planning guidance. Waiting past this window doesn't just complicate paperwork; it can close off the option of a signed agreement entirely.
What the Agreement Must Specify at Each Stage
The services a caregiver agreement needs to spell out change as dementia progresses. Early-stage agreements can focus on household help and transportation. As the person declines, agreements need to address supervision, bathing, dressing, and incontinence care instead, according to Dementia Care Central. Clinicians track this progression using staging tools like the Global Deterioration Scale (GDS) and the FAST scale.
The GDS defines stages 4 through 7 as dementia itself, and states that beginning at stage 5, the person can no longer survive without assistance, according to Pathways Health's caregiver staging guide. That stage 5 threshold is typically where a caregiver agreement has to shift from part-time help to comprehensive, round-the-clock-oriented terms. Because the scope of care changes this much, an agreement written at diagnosis often needs its services and pay rate revisited as the person moves through stages. Sources recommend reviewing and revising the agreement over time, since changes in condition — and in state law — affect how the documents and payment terms should be structured, according to Alzheimer's Association guidance summarized by Next Avenue.
Why a Written Agreement Protects Medicaid Eligibility
A written personal care agreement, signed before any payments begin, documents that payments to a family caregiver are compensation for defined services rather than a gift. That distinction matters because Medicaid applies a five-year look-back period in most states, and an undocumented family payment can be treated as a disqualifying transfer, according to Medicaid Planning Assistance.
Dementia Care Central documents a case where a family paid a caregiver roughly $19,000 from a grandmother's assets under an informal, unwritten arrangement. Because there was no signed agreement, the undocumented payments complicated her Medicaid application after she later entered a nursing home, according to Dementia Care Central. The lesson applies regardless of stage: a family paying a relative for care at any point needs the agreement signed and dated before money changes hands, not after.
What to Do Before Each Stage Transition
A caregiver agreement isn't a one-time document. Treat it as something to revisit at each stage change, with specific steps:.
- Sign the core legal documents — power of attorney, healthcare directive, and the care agreement itself — as soon as possible after diagnosis, while the person can still participate, per the Alzheimer's Association.
- Define early-stage duties narrowly (household tasks, transportation, errands) rather than writing vague, open-ended terms.
- Revisit the agreement's scope and pay rate as supervision, bathing, dressing, or incontinence care become necessary, since these are the services later stages add.
- Confirm the agreement is signed and dated before any payment is made, to keep it usable as Medicaid documentation.
- Watch for the GDS stage 5 threshold — when the person can no longer survive without assistance — as the point to rewrite the agreement for comprehensive care rather than part-time help.
State Programs Can Supplement a Private Agreement
Some states now offer dementia-specific alternatives to a private family agreement. Nevada's Medicaid home- and community-based waiver manual created a "structured family caregiving" benefit specifically for people with dementia or related conditions, covering case management and respite in addition to paid family caregiving, effective June 1, 2025, according to Nevada's Division of Health Care Financing and Policy.
Programs like this are stage-aware by design, built around the same progression from lighter support to comprehensive care that a private agreement has to track. Families drafting their own agreement should check whether their state runs a similar program before assuming a private contract is the only option.
Frequently Asked Questions
Can a person with moderate or severe dementia still sign a caregiver agreement?
Generally no — signing requires legal capacity, which later-stage decline typically removes, according to Caring.com's attorney-nurse guidance.
What happens if a family pays a relative caregiver without a written agreement?
The payments can be treated as a disqualifying Medicaid transfer during the five-year look-back period, as documented in the $19,000 case reported by Dementia Care Central.
