Partnership Name Change?

Have you got a partnership agreement? If so it should provide for how partners can transfer their shares, if at all. If you don't have a written agreement, partnership law usually requires that partners have to unanimously agree on any transfer or change, because partners are liable for each others debts and agreements, so each partner is entitled to decide who will be a partner and whose liabilities they'll take on.

You should consult a business lawyer to help you work this out.
