Hi Everton and welcome to the forum
If you go bankrupt, it is only your share of the equity which will need to be handed over the the Trustee so your husband can keep his share.
So long as your pension contributions are reasonable, it is unlikley that the OR will insist that these be stopped.
Your car will be looked at by the OR, and if it is worth more than £3,500 you can expect it to be taken from you and sold. You will be allowed a modest allowance to purchase a replacement vehicle - perhaps between £2,000 and £2,500. Are both cars registered in your name at the moment?
