I assume you mean legal costs. In that case, the lead investor will ask for between $10,000 - $15,000 in legal costs. The Company's legal costs could run from $15,000 all the way up to $50,000 depending on the complexities involved in completing the deal. But these are costs associated with a priced round with a lead.
If you're raising under $1,000,000, it's best to raise a convertible note where you can use a standard convertible note doc and really spend no more than a couple of thousand (if that much) on legal fees.
Happy to talk this through in a call.
