I agree with those who have adviced our lucky inheritor to first obtain documentations to ensure that the land is officially in thier names. If he has no lawyer he can visit the offices of Public Trustee in Sheria House 6th floor for advice.

Like many pple have said get the land registered in your name and since you have already been saving, once you have settled down and done some soul searching as to what you want, do some math as to whether the cash u have can develop the land like if the land is suitable for rental houses, how much they will cost to develop and if you have that kind of money.If you have then go ahead and develop. If not keep on saving till it's enough to develop hata kama ni one floor assuming you choose to go that way.

I suggest you don't sell even a centimetre of the land unless you really have to.(eg sell an acre in shags n buy and develop in a prime area.)But be careful with this also.
Relatives are good but I suggest you don't involve them in this.
Don't even allow them to be farming on it since its just idle it'll just bring conflicts.
(Infact it's only a matter of time before you get pple claiming that in your tradition girls don't inherit and they will mostly be relatives.)
Do not use the land as collateral for your spouses/boyfies loan no matter how you love them. They will refuse to pay and it will be auctioned.
About donating to the church, I would consider the following:
Did I use to go to the same church with my dad? If yes, why didn't he donate some to them?
How would my dad take it if he learns what I have done?
Has the church actually been in need of land? What steps were they taking towards addressing that?
If they had not been taking any action to acquire land then they are just creating needs that don't exist.
If on the other hand they required land, and have been acting on it they should still continue.
Lastly if you for whatever reason(I doubt if there is any) have to donate to the church it shall not be more than 10 percent of the total land.
Wish you all the best and please for the sake of your dad, he denied himself so many things so he can give this land to you. Don't let him down.

Thats one lucky girl! Continue with your earlier project, depending on inheritance has left many people stagnant. DO NOT give that land or a section of it to any church unless it is out of freewill. God loves a cheerful giver! Christians do tithe but we do not tithe from inheritance but from the increase(read revenue) from our toil.

Be careful with these church leaders.

This captures what i'd say. I'm a mother and whatever i do, i'd like to leave something for my children-as their mum. My dad gave us land too. I've never sold it and i feel nice about that. Sometime my children will enjoy their grandfather's land too-and on and on. Also on the church, i'd not be quick to donate land but weigh and know if i'd really want to do that. I also wonder why your dad never donated. If he's alive, discuss it with him. If not, ask God for wisdom. He freely gives to those who ask Him. That's a promise in the bible.
