Thinking About Moving in With Family? Why a Granny Flat Agreement Matters.

As parents get older, many families start thinking about whether Mum or Dad should move in with an adult child, build a granny flat, or contribute money towards renovations or a larger home.

These arrangements can work very well. They can provide companionship, practical support and peace of mind for everyone involved. However, when significant money or property is involved, it is important to treat the arrangement as more than an informal family understanding.

A written granny flat agreement can help protect the older parent, the adult child and the wider family.

What is a granny flat agreement?

A granny flat agreement is a legal arrangement that records the terms under which an older person will live in a property owned by someone else, often an adult child or another family member.

Despite the name, it does not always involve a separate “granny flat”. The arrangement may involve a parent living in a room, self-contained area or separate dwelling on the property.

In many cases, the parent may contribute money towards the arrangement. This could include paying for renovations, contributing to the purchase of a property, transferring ownership of their home, or providing funds in exchange for the right to live at the property for life.

Why informal family arrangements can cause problems

At the start, everyone may be on good terms and assume the arrangement will be straightforward. Unfortunately, circumstances can change.

Problems may arise if:

  • the adult child separates or divorces
  • the property needs to be sold
  • the older parent’s care needs increase
  • the relationship between family members breaks down
  • one person becomes ill or loses capacity
  • there is disagreement between siblings
  • the older parent needs to move into residential aged care
  • someone dies unexpectedly.

Without a clear written agreement, it can be difficult to prove what was intended. This can leave the older parent vulnerable and may also create disputes between family members.

What should a granny flat agreement cover?

A properly prepared agreement should be tailored to the family’s circumstances. It may deal with:

  • where the parent will live
  • whether the parent has a right to live there for life
  • what financial contribution is being made
  • who owns the property
  • who pays for rates, utilities, insurance and maintenance
  • what happens if the property is sold
  • what happens if the parent needs aged care
  • whether the parent can have visitors or receive care at the property
  • what happens if the adult child separates, becomes bankrupt or dies
  • whether any money is to be repaid in certain circumstances.

The agreement should also be considered alongside the parent’s Will, estate plan, superannuation arrangements and any enduring power of attorney or guardianship documents.

Centrelink and tax issues

Granny flat arrangements may also have Centrelink and tax implications. Services Australia treats a granny flat interest as an arrangement that gives a person accommodation for life, and this can affect pension entitlements or the assets test. The Australian Taxation Office also has rules dealing with capital gains tax for granny flat arrangements.

For this reason, it is important to obtain legal, financial and tax advice before money is transferred or documents are signed.

Why legal advice should be obtained early

A granny flat agreement is easiest to put in place before the arrangement begins. Once money has changed hands or a parent has sold their home, it can be much harder to resolve disagreements.

Independent legal advice is particularly important because the interests of the parent and the adult child may not always be the same. Each person should understand their rights, obligations and the possible consequences if circumstances change.

Protecting family relationships

Putting the agreement in writing does not mean the family expects something to go wrong. It simply provides clarity.

A well-drafted granny flat agreement can reduce uncertainty, protect the older parent’s housing security, and help avoid disputes between siblings or other family members later on.

If you are considering having a parent move in with you, or you are an older person thinking about contributing money towards a family member’s home, it is important to get advice before the arrangement is finalised.
