Financial arrangements. Does this sound fair?

[MsAR]

I'm questioning whether I'm being reasonable over this and would really appreciate some outside opinions.

I not married to my partner. Neither of us really believe in it and are quite happy as we are. We're buying a new house together and as I have the larger share of the deposit I've asked that the money is protected in a deed of trust in case we did ever split.

We earn the same (good) salary and put the same amount into a joint account every month to pay for mortgage and bills. This leaves us with the same amount of disposable income.

I'm pregnant and will obviously be on a reduced income for a few months so I've asked that we adjust the amounts going into the joint account so that he pays more and we still have the same amount of reduced spending money. I'm convinced this is the right thing to do but am worried I'm being selfish about my deposit. Am I being unfair?

How long are you intending to have a reduced income for?

I think it's fair provided you both pay for the child 50/50 over the long term, otherwise he'd be subsidising you which is something you don't seem to like the idea of.

Poppy, thank you for your advice.

We are planning for me to take 8 months maternity then I'll be back on the same income. If his income was ever reduced, I'd want to put more in than him. For about a year I did actually contribute more to our rent as I earned more.

It's the deposit thing that has got to me a bit. He accepted it straight away and we have a strong relationship but you never know what might happen in the future so I'm trying to protect what I've built up just in case.

When my partner and I bought our house, I put down a larger deposits and we share the mortgage so own the house 70:30.
We put 55% of our (roughly similar) monthly salary into a joint account for joint (house, bills, groceries) spending.
I'm on ML at the moment and what we agreed was that we both continue to put 55%, in my case of SMP, into the joint pot. Seriously, my only outgoings are my mobile phone bill, £5/week for a buggybootcamp class and a few coffee shop coffees/cakes! I just go to the free baby classes with my wee one. The two months 'free' CT gave us a bit of a buffer and we've cut back on other spending.
I would suggest you want to protect your deposit as a % of the house price, rather than a fixed cash amount. £20k today will not be the same as £20k in 10 years time. It is also imperative that you both get Wills, and investigate the difference between 'joint tenants' and 'tenants in common'. Can't remember which one you need.
Someone will be along shortly to advise I'm sure (or post in legal).
In answer to your direct question, your deposit is a completely separate issue to your (short term) reduction in income. You wouldn't have been able to buy your property/get your mortgage deal without it, and you may not have been able to fall pregnant.
