I am a dinosaur (having moved into non-accounting work and we were still using SSAPs then), but let me take a crack at it. Please anyone correct me if I am wrong, but I thought I should have a go so as to start the ball rolling, and also (re)educate myself.
Re. the limited company, it depends on whether you are merely buying the assets (and/or liabilities) or shares of the entity.
If buying the shares, you simply
Dr. Investment
Cr. Cash/bank (if owners of acquired company is paid in cash) or Share Capital (if shares are issued to acquire shares of the limited company)
Depending on the degree of control (subsidiary or associate), you will prepare group accounts accordingly.
If buying assets,
Dr. Assets and liabilities (of diffferent categories)
Cr Entry is same as the above
Re. partnership, it also depends. If you are acquiring the entire partnership (and it ceases to exist after that), you are buying the assets and/or liabilities. But if you are buying into a partnership (i.e. being admitted as a new partner without a dissolution), it would be treated as an investment in your company's books (but as an addition of partners in the partnership's books).
(Now if you have a controlling interest in the partnership, I believe you may have to consolidate the results as if it was a subsidiary. Could someone please cite the relevant FRS/IAS?)
Any other complications to these transactions are above my pay-grade and low intellectual capacity not to mention my poor memory.....
