They aren't living in an independent household and sharing living costs by the sound of it. Cohabitation is really only relevant in terms of shared housing and living costs. Your ex will still have housing and income needs which should be considered when finances are settled.
In a short childless marriage the general rule of thumb is that you take out what you put in. There may be some variance around marital debt if one party earns considerably more than the other and debts were taken on with this in mind.
As to paying the mortgage, whoever remains in the property would be expected to pay that and running costs. It is counted as \"rent\" for the half owned by the absent party.
sorry for the confusion!!! my partner and I use this forum as both going through a divorce and share a computer. shes asked me to ask from her partners point of view as didn't want to be judged. I said she was being silly but she insisted. she is a t1t at times.
the mortgage part makes a lot of sense!
well this is what shes worrying about. They had an expensive wedding because he wanted to pay for everyone's flights and accommodation. now shes panicking because she's liable for half regardless to who wanted what at the wedding. But he was earning 3x more than she was and got the loan in his name. so this will be considered then? as she will struggle to pay that back.
