Reply with "I haven't decided yet." but still prepare for it anyway. Give no absolutes of your motives or intentions. Your lawyer is your business not hers until they get together and hammer out a deal for dissolution and equitible split. Don't even acknowledge the lawyer questions or are you going to file questions. Just say I haven't decided yet and ask for the receipts anyway for your record-keeping since you are paying for half of it. She probably is temp checking because she's unprepared to file unless she has already seen a lawyer and retained them.
