One to watch is the Enterprise and Regulatory Reform Bill from Vince Cable's BIS department - where intra-coalition tensions could appear clause by clause.
On the Defamation Bill, the government will have to decide whether to accept a new clause allowing profit-making organisations to sue for defamation only where they can prove substantial financial loss, and barring public bodies - like local authorities - from taking any defamation action.
Peers then turn to the third reading of the Growth and Infrastructure Bill - where there may be an attempt to press an amendment for a "sunset clause" on the changes it makes to planning powers to impose a quota for affordable housing in new developments.
