How do you deal with leased assets when incorporating a sole trade or partnership?

Can anyone help please with the practicalities of how to deal with the transfer of leased assets on incorporation from a sole trade/ partnership. I am particularly concerned with continuing to get  tax relief but any considerations for the accounts would also be welcome please. I am concerned that the leases would continue to be in the soletrade/partnership name unless it was re-negotiated with the finance companies which is going to be costly.
