In New Zealand, the Property (Relationships) Act 1976 governs how assets are divided in a separation. The Act dictates that once you have been together for three years, your assets and debts become "relationship property" which are divided equally between you if you separate. This includes assets like property, bank account balances, superannuation, cars and furniture.
There are some assets which remain "separate property" and don't need to be shared. These include money in bank accounts which existed prior to the relationship, and that are kept separate from the relationship and do not contain income earned during the relationship. They also include any portion of superannuation (including Kiwisaver) which is acquired prior to the relationship.
Overseas Property
Only some property held overseas is covered by NZ law.
Within the Act, overseas assets are classified as either "movable" or "immovable" property. Movable property includes superannuation, vehicles and bank accounts. Immoveable property includes land (with or without a building), fixtures and leasehold interests in land.
The general rule is that the New Zealand Courts do not have jurisdiction to deal with immovable property that is not in New Zealand.
The only exception is where a couple agrees in writing that New Zealand law should apply. Such an agreement needs to comply with the rules and formalities of the other country's laws.
Your situation
Your husband's flat in London is immovable property and therefore is not covered by New Zealand law. Ownership of the flat will be dependent on the relationship property laws of the United Kingdom.
However, his bank account is moveable property and is therefore covered by New Zealand law. You may be entitled to a share of this – unless the funds were accumulated before your relationship began and have been kept separate from any income earned during your relationship.
The superannuation is also classified as movable property. The portion that has accumulated since your relationship began is relationship property and will need to be shared equally with you.
Next steps
New Zealand Courts can make orders regarding the division of the movable property. However, I always recommend that people try and reach agreement out of Court if they can, as going to Court can be expensive, stressful and take a long time to reach a conclusion.
Since your situation is somewhat complicated, I would advise you to seek legal advice from a New Zealand lawyer. Provide them with as much information as you can about the assets belonging to you and your husband, both here and overseas. You may also wish to seek advice from a lawyer in the UK.
Then I recommend that you and your husband try to reach agreement on your relationship property. You can do this through discussion between the two of you, or in a round table meeting with your lawyers.
Summary
When your relationship property includes overseas assets, you need to be aware that New Zealand law may not govern how these are split in a separation. If you want to be sure that you have an equal share, you either need to have a prenuptial agreement in place, or have a formal legal agreement with your spouse or partner that New Zealand laws will apply to your relationship property if you separate.
