Living expenses / beneficial interest in property

Hello,

Could anyone help me with things to claim on for living expenses?
My situation is facing sequestration / bankruptcy very soon!

Average pay per month £1600

Own my house approx £8k equity

I’m expecting a child next month

Would just like to know how much I would have available ?
Also what would the circumstances be around beneficial interest with my wife being 50% owner in My household ?

Anyone with any info would be appreciated
