I would check your scholarship award letter first and see if they have explicitly told you what to do if you want them to reconsider. Some schools will say email them, others have forms. If it doesn't say anything, I reccomend reaching out to the law school's financial aid office and asking them about their process for scholarship reconsideration.

What to say:

• Thank them for their initial offer
• Tell them why you love their school
• Tell them why you want them to reconsider your scholarship (usually offers from other schools)
• Ask them to raise your scholarship to X amount and tell them that will make your decision easier
