Contracts are drafted in so many different scenarios that it would be impossible to provide a definitive list.
Contracts arise in the most personal of affairs (prenuptial agreements, organ donation), everyday situations (leases for dwellings and commercial offices) and in financially important transactions (purchase of properties and businesses).
When living in other countries, local laws can impinge on how a contract may be drafted which makes it even more important for a local lawyer to advise you on how to ensure that your rights are protected.
