He has bad credit as a result of his previous marriage and also filed for bankruptcy  due to ex's cancer bills.

The husband had a previous marriage with children and one of them was living with him while he was alive. 

Your marriage is WAY more important than this.

Sometimes spouses get out of bad situations with their ex's and now are trying to figure out life outside of that marriage.

I am interpreting this to be per person and that there is not a marriage penalty.  

In Texas this, signed by witnesses that knew the deceived for a very long time is necessary, but it gets messy when combined with other heirs marriages, divorces and deaths.

It's like being required to stay in an arranged marriage for 5 years, when you never met the person before in your life.

I am needing some advice about a potential deal and to see what options I might have.My aunt, by marriage, is trying to get rid of her mother's house, because she is now living in a nursing home. 

I would probably not get married but if I did it would need to be a like minded investor that brought her own investments to the marriage (love is only a state of mind and highly over rated).

You might meet the right person tomorrow, but partnerships are like marriage, and of all the girls I've dated, I only married ONE.
