DTC T2201 Application Part A Legal Rep

As a Tax Preparer representing a client, can I complete Part A of T2201 as their legal representative?
Thanks!

That’s an interesting question!
If the claim for the DTC credit is 100% true and valid, you could still face being sued by the client (they would win), and it is hard to figure out what CRA would do about a false claim of being a legal representative.

If the claim is not 100% ok, you could run into a serious Section 239 (1.1) Offence from CRA.

But even if you had a POA from the client, why would you not ask the client to live their own life, sign their own forms, carry their own responsibility and liability?
