Consent letters are applicable in a variety of situations. Among those situations are giving permission to a babysitter to authorise needed medical attention, giving permission for your child to travel overseas with another relative or divorced parent, allowing another person or company to use your business trademark or allowing a minor to do a task the law doesn't entitle them to, like getting married.
Address the letter "To Whom it May Concern" or, if known, the specific recipient of the letter.
Explain the task, trip or right for which you are granting permission, including expected dates if it involves travel. Include any information that the recipient might need to know. For example, in the case of giving permission for a babysitter to authorise medical treatment, include the child's insurance information and primary doctor.
Write a specific consent statement including the full names of both parties involved such as: "I, (insert full name) give my consent to (full name) to (activity)."
Sign and date the letter in front of a witness who is not the person you're granting permission. Ask the witness to sign and date the letter.
Specifically list the expected dates of travel for cases of minors travelling abroad. Include the contact information of the parent staying in the country.
