Custody, guardianship and division of assets in a divorce

I want to divorce my husband; my concerns are as below;

If the divorce proceeding is under Sharia Law, what are my chances when it comes to;

1. Child Custody & guardianship - I believe I will get the custody until age 11. My question is if the husband is unemployed for 6 months now, can he still be considered as guardian since he can't provide for the family?

And if I can show that he has never been a provider for the family (basically, I pay ALL the bills since we got married) & I have a proof that he had an affair a year ago, can I get the guardianship as well & full custody?

Can the child get an opportunity to choose where he wants to live with when he reaches puberty?

2. DIVISION OF ASSETS - Since I got a land inheritance from my parents, is he entitled to get 1/2 of the property?

Obviously, he has no house/properties in his home country as well as savings and I am worried he will get everything. I own 50/50 in which he didn't sweat a dime on it.

Awaiting your advice.
