While a written agreement, preferably signed by both parties, is usually gold, we know that sometimes in business the day-to-day reality can differ from the legal ideal. That is why even in the absence of a clear written agreement, we can advise on your rights and prospects of success based on supporting documents such as emails, text messages, purchase orders, proof of delivery and invoices. Even a part-payment can be crucial evidence in your case, or you may have an equitable quantum meruit (fair value) claim. Having lawyers who can think outside the square and know the intricacies of commercial law is essential for the trickier types of claims.
