If you have a new partner and you know what his or her financial position is, then you have to disclose this, but only if you plan to live together or remarry in the foreseeable future.
It is not taken into account directly. Your spouse or ex-spouse cannot ask your new partner to pay over any income or capital. There are no claims directly against your new partner’s finances.
But it does make a difference indirectly. If you are living with somebody and sharing your bills and housing costs then your income – and possibly your capital – is more available to pay to your ex-spouse. Your financial resources can go further.
It is possible, but very rare, for your partner to be asked to produce evidence of his or her finances in court. However, judges are reluctant to let this happen unless it is absolutely necessary.
It is often best to acknowledge that your finances are shared with your new partner. This can be done by showing that your outgoings are shared.
