According to the FATF typology report 2000-20011, lawyers can provide a range of functions that can be useful to a potential money launderer, such as:

Creating complex legal arrangements, such as trusts, foundations, or corporations, that can obscure the identity and ownership of the beneficial owners or the origin and destination of the funds.

Buying and selling property, such as real estate, art, or jewelry, that can be used to transfer or store illicit proceeds or to provide a legitimate cover for the source of funds.

Performing financial transactions on behalf of a client, such as opening bank accounts, transferring funds, issuing checks, or exchanging currencies, that can facilitate the movement or concealment of illicit funds.

Providing legal advice, on the other hand, is not a function that can be directly exploited by a money launderer, unless the advice is related to the above functions or to the avoidance or evasion of anti-money laundering laws and regulations.
