I need to write an example with "hand something over". Can you please help me?

1) I'll hand over the line (??) to the studio in Glasgow.
2) Have you ever had to lend him your book?
Is this possible?
3) Did you ever have to lend him your book?

This sentence was in your previous post: "6) He handed his winnings over to her."

It's correct.

Here are other possibilities:

I'll hand over control of the accounts to the studio in Glasgow.

I'll hand over all my paperwork in the morning.

She handed over all the money she had stolen.

Sentences 2 and 3 are fine.
