Sorry for your lose.

One of the things I love about Nigeria is with money anything is possible.

Try to dance to their tune and fix a date two days later frame them anonymously and get them arrested for serious crime. Let the police transfer their case to outside your state.

While they are in detention do your father's burial.

After the burial release them and come back to thank me.

What manner of conningness is this? This will ultimately bring more trouble than any slight solution it might bring.

The fact that the late father got all the properties while there were other males in the family is what still rubs me the wrong way. Like, how's that even done?

They apparently finally want a share of the property, and if OP claims that his father didn't have the chance to share it while he was alive (I wonder how long he had it all), now is his chance to do better than his father and share it.
