When it comes to talking business and considering risk, often the last thing that comes to mind is what might happen to the business if a personal relationship ends. While it might not be front of mind, it is still an essential consideration as New Zealand relationship property law can turn a business into a battleground in the event of separation.
Under the Property (Relationships) Act 1976 (PRA), relationship property generally includes the family home, family chattels, all income earned during the relationship and assets acquired during the relationship (relationship property). On the contrary, separate property is defined as all property of either partner that is not relationship property, and includes property acquired prior to the relationship, property acquired out of separate property or an increase in value of separate property (separate property).
Upon the end of a qualifying relationship (marriage, civil union, or de facto relationship of over three years), the general presumption is that all relationship property will be equally divided while separate property will be retained by the owner of that property.
It is a common misconception that if a person owns their own business (and whether they operate as a sole trader or through a company or other entity) it is their separate property. Unfortunately, this is not always the case. Regardless of how a business is owned, and whether or not both partners are involved, it may be considered relationship property. Some examples of where a business may be considered relationship property are:
If your business is relationship property, and you and your partner separate, you will need to jointly decide who will retain it or how it will be divided. This could involve selling the business and dividing the proceeds or one of you buying out the other for an agreed sum (usually after obtaining specialist valuation advice from a business valuer). In the worst-case scenario, if you and your partner cannot agree, the future of the business could end up in the hands of the courts.
There are safeguards that can be put in place to pre-empt what should happen to the business in the event of separation. The most effective way to do this is to sign a contracting out agreement (COA) with your partner either during the early stages of your relationship or of the business. A COA allows you and your partner to opt out of the PRA’s default rules, meaning that you can agree what will be relationship property and what will be separate property.
Without a COA, some other options and considerations are set out below:
Too often business owners only learn about the implications of relationship property law once it is too late, at the point they engage a lawyer because of a separation. By being aware and taking active steps to protect your business, you can put yourself (and your business) in a better position, should you ultimately experience a relationship breakdown.
