Why would my brother the exectutor get a lawyer after our last living parent died?

Your brother, as the executor, may seek legal counsel to navigate the complexities of estate administration, including interpreting the will, managing assets, and ensuring compliance with state laws. A lawyer can help address any disputes among heirs, clarify the executor's responsibilities, and assist with tax implications. This legal support can mitigate potential liabilities and ensure that the estate is settled efficiently and fairly.
