Payment of tier on group owned land

[SnowGryphon]

My friend and I formed a group to share expenses.  She donated and deeded land to the group.  We are both owners of the group and there are a few more group members.  When tier payments on the land are to be paid, will the payments come from both owners of the group, or only from my friend who donated it to the group?

Thanks in advance for your consideration.

Only the owners who donated tier are charged.
