Top Law Schools

Like a lot of people on the site, I'm currently trying to decide between several good schools. Thanks to all the advice that I've seen here, I'm trying to encourage a robust competition between all of these schools to offer more scholarship money. However I'm currently feeling the pressure of various deadlines that require me to pick a school--the SEO internship, third party grant and scholarship applications, the accelerated deposit deadlines that schools attach to scholarship awards, etc. For instance, I've received a 75K scholarship offer from a T14, but I need to answer them by the 21st, and I still haven't heard back from my top choices.

I hoped I could ask a few questions:

1.) Are you allowed to extend deposit deadlines (in particular, those attached to scholarships)?
2.) I've heard that some people are negotiating into June or July. Are people putting down multiple seat deposits?
3.) A lot of outside scholarship/grant agencies will ask for proof of enrollment/what school you'll be attending. What's the best way to address the fact that you haven't chosen a school yet?
4.) Will schools respond to the deadlines of other schools? i.e. "I have an April 21 deposit deadline, I need to know soon whether or not you will offer something."

Those are all the specific questions. Any other general tips on scholarship negotiation would be greatly appreciated!

1.) You're allowed to ask for whatever you want. They're allowed to say no, but that's the worst that can really happen.
2.) Absolutely.
3.) If they require proof of enrollment, you probably can't apply for those until you choose a school, but it couldn't hurt to contact the organization and find out for sure.
4.) Yeah, schools do this all the time. Obviously that's not to say every school will every time.

General tips: Always try to come across like whatever school you're talking to is your top choice and if they could just raise your offer, match another offer, extend a deadline, whatever, you'd have a much easier time making your decision. Never tell a school "X school offered me more money, so the only way I would go to your school is if you offered me $Y" or anything similar. It won't work out for you. Negotiate with multiple schools based on multiple other offers multiple times. Don't just take all of your offers to one school, see what they say, then take your offers to the next school, and so on. Pick schools that are particularly competitive/obvious peers, and start trying to get one to move on their offer based on the other's. Once they do, turn around and get the other to come up. Then try the first school again. Go through as many rounds of negotiations as you can until they say definitively that they will not reconsider their offer. Keep doing this for all of your school pairings that make sense.

Good luck!
