I brought significant property into the relationship. Can my spouse claim any of it?
Property divisions are based on the contributions made by each party to the relationship.
In a short relationship, each party will tend to leave the relationship with what they brought to the relationship.
In a long relationship, the ongoing contributions made throughout the relationship are seen to decrease the significance any financial contributions made at the beginning of the relationship by an individual party. The continuing financial and non-financial contributions made by both parties to the relationship tend to erode the ability for any particular asset to continue being owned exclusively by one party or the other.
