IIRC, Howard is her personal-affairs lawyer and not the guy(s) who represented her in front of SCOTUS.
I think Howard's only there because Anna likes him. She needs PROFESSIONAL representation.
Now she has an urgent need for a high-powered lawyer, but what she expected to need when she got down there was no more than a regular lawyer familiar with complex personal finances, to deal with the financial legalities of the new baby having come into the picture, setting up the baby with whatever citizenship and travel documentation is desired (quite possibly dual US/Bahamas citizenship, and maybe Bahamas residency for tax purposes), etc.
