A contract is a legally enforceable agreement between two or more parties. It is usually binding when there is an offer, acceptance, clear terms, and an exchange of value (consideration).

Many everyday agreements can be verbal and still enforceable, but some types (such as real estate contracts and certain long‑term agreements) must be in writing under the statute of frauds. A written contract also makes it much easier to prove what was agreed.

Online templates can be a starting point, but they are not tailored to your state law, situation, or your specific business risks. It is usually wise to have a lawyer customize your key contracts so they actually match how you operate.

Watch for automatic renewals, one‑sided indemnity or liability clauses, broad non‑compete or non‑solicit language, and harsh default or termination provisions. You should also confirm that the written terms match what you discussed.

Yes, but changes should be made in a written amendment or addendum signed by all parties. Email exchanges alone may not clearly or cleanly update the original agreement.
