My partner and I never married, do I have any rights to the house?

Yes, you may have a strong claim. Under the Property (Relationships) Act 1976, de facto partners are treated the same as married partners if they have lived together in a relationship in the nature of marriage for at least three years, or have a child together or made a substantial contribution to the relationship. The family home is relationship property regardless of whose name it is in, and would generally be divided equally. You can try to negotiate an agreement, ideally in writing with each of you receiving independent legal advice, or apply to the Family Court. To protect yourself, a lawyer can register a notice of claim or caveat against the title so it cannot be sold without your knowledge. Keep evidence of your contributions.
