Understanding Your Legal Rights

When buying a house with a partner without the legal framework of marriage, understanding your rights is crucial. In Australia, property ownership is typically governed by either joint tenancy or tenancy in common.

  • Joint Tenancy: This means both partners have equal ownership and rights to the property. If one partner passes away, the other automatically inherits the other’s share.
  • Tenancy in Common: This arrangement allows for ownership to be split unevenly. Partners can own different percentages of the property, and each can will their share to someone else upon their passing.
Considering how you wish to structure ownership is a vital first step in the home-buying process.

Preparing Financially

Buying property requires significant financial preparation. Here are key steps to ensure you're financially ready:

  • Credit Scores: Both partners should review and, if necessary, improve their credit scores before applying for a mortgage. Australian lenders often require a minimum credit score of 620, though this can vary.
  • Deposit Requirements: Typically, Australian lenders need a minimum deposit of 5-20% of the property's purchase price. However, aiming for a 20% deposit can help avoid Lenders Mortgage Insurance (LMI).
  • Budgeting: Establish a comprehensive budget that includes potential mortgage repayments, property taxes, utilities, and maintenance costs.

Setting Up a Cohabitation Agreement

A cohabitation agreement is a legal document outlining each partner’s rights and responsibilities regarding the property. This agreement can cover aspects such as:

  • Financial contributions, including mortgage repayments and maintenance
  • Decision-making processes for property-related matters
  • What happens if the relationship ends
Having a cohabitation agreement in place can prevent disputes and provide clarity if the relationship changes.

Seeking Professional Advice

It’s advisable to consult with professionals who can provide tailored advice:

  • Mortgage Brokers: A mortgage broker can help you find suitable loan options and navigate the application process.
  • Solicitors: A solicitor can assist in drafting a cohabitation agreement and ensure all legal aspects of the purchase are handled correctly.
  • Financial Advisors: They can offer guidance on managing your finances and investment strategies as homeowners.

Common Mistakes to Avoid

1. Not Clarifying Ownership Structure: Failing to decide between joint tenancy and tenancy in common can lead to complications later. 2. Ignoring Financial Compatibility: Ensure both partners are transparent about their financial situations and have aligned financial goals.

3. Overlooking a Cohabitation Agreement: Not having a legal agreement can lead to disputes if the relationship ends.

4. Neglecting Professional Advice: Skipping consultations with experts can result in costly mistakes.
