If Mr. A hired Attorney B to draft a will, and names Mrs. C to be the beneficiary. When Mr. A died, it was discovered that the will was improperly drafted, violated state law, and was therefore ineffective.

Mrs. C did not receive the money that she would have received had the will been valid. Mrs. C sued Attorney B for breach of the Mr. A -Attorney B contract to recover what

she would have received under the will.

What rule on breach of contract can be applied? and why?
