Sorry - not necessarily the same, as Coayuco says above. I do look after and care for my mother in her old age. The lawyer I would 'take care of', as in 'pay him off'. But i don't necessarily 'care for' him, as in, 'like him personally'. So perhaps DL should accept both as we don't have enough context to determine what is really being conveyed.
Say there is a situation requiring a litigation. The woman takes care of the lawyer = goes through the bother of finding and hiring the lawyer. Another person, for example, might be taking care of gathering necessary papers for the case. "Taking care of one's business" is the implied meaning here.
Because my granddaughter is also working for a barrister while doing her law degree, I saw 'takes care of' as meaning makes sure he remembers his appointments, has the correct papers in front of him when he needs them, books his train tickets etc. But without context it could be any of the things suggested on this thread.
