Blue is the norm. Do not use a pencil because someone might handle it, and avoid red ink, as it can be difficult to read. Make sure that both parties sign the agreement and that the document is recognized by two witnesses or a notary for both parties who rely on the document to verify its credibility. If an agreement is illegal, it is unenforceable and you can break it without legal penalties. Even if an agreement has too many restrictions, what we see in restrictive alliances that are too long or too long. Under these conditions, you can avoid these restrictions without sanctions. However, the uncertainty of these situations is unfortunate and it is only when you actually go before a judge that you will finally know if they are enforceable or not. Contracts are agreements that set conditions and are intended to hold each party to account. They normally need to be signed by both the sender and receiver to activate the terms of the agreement, show that they accept the terms of the contract and make them valid, although there are some forms of contracts that do not necessarily have to be signed for a court to find the contract valid. It is important to be very detailed in the signed agreements, what is allowed and what is not, and not to depend entirely on the general law. If an agreement is illegal, it is unenforceable.
If an agreement is too broad, the contract can be cancelled, even in the absence of legal force. Since the uncertainty of any agreement is possible, you will only be able to understand after the court whether an agreement is applicable or not. Liquidators are entitled to refuse dependent contracts that allow them to break agreements to this effect.
