Introduction: What is a Consent Letter?

A consent letter is a written document that permits a particular activity or action. It acts as a valid proof that the person or party granting the consent is aware of and agrees to the specified terms. Whether it’s a parent allowing their child to travel, a patient authorising medical treatment, or an individual permitting their data to be shared, a well-shared consent letter is the essential requirement for clarity and accountability.

Key Components of a Consent Letter

• Full name and contact details of the person giving consent
• A clear statement of consent
• Detailed information about the activity or action
• Contact information of the person receiving consent
• Signatures and dates (witnesses and notarisation at other times)

Situations when a Consent Letter is Required

Here are some common scenarios wherein a consent letter is required and is valid:

• When a child/minor is travelling alone, or with one parent, many countries and airlines require one of the non-travelling parent or a legal guardian.
• Parents and legal guardians may need to give a signed consent letter for their children to receive medical aid, especially in emergencies. The same applies to adults as well.
• Schools require a signed letter from parents or legal guardians giving consent for field trips, off-campus events, or participation in competitions.
• Parents or legal guardians may have to provide one for minors to take up temporary employment or internships.
• In businesses, a signed consent letter is required for authorising the sharing of personal and confidential data.

Guidelines for Writing a Consent Letter

Given below are certain guidelines that will help you write an effective consent letter:

• The letter or email should have a clear heading regarding the consent.
• Clearly describe the requirements (if any).
• Ensure that relevant names and other details, such as addresses and contact information of the respective parties, are included in the letter.
• Mention the duration of the program or participation.
• Explain the rules of the contract.
• The most important part is the signature on the consent letter. This is where the respondent accepts the consent.
• End the letter in a professional tone.

Types of Consent Letter

There are three distinct types of consent that an organization may collect:

• Explicit Consent: This type of consent is also known as direct consent. In this type of consent letter, an individual provides a positive indication that they agree to their data being shared. This includes options like ticking an opt-in box, or an action that signifies agreement, such as oral confirmation, or the provision of contact details where the individual has been informed that by giving these details, they agree to their data being shared.
• Implicit Consent: This type of consent is also known as indirect consent. It is described from the action of the respondents. This is when someone gives their contact information (e.g., email address, phone number, etc.) but does not explicitly say they want to receive marketing messages or mail. An example of implicit consent is when a customer makes a purchase and provides their email at checkout.
• Opt-out Consent: Opt-out consent is a method of obtaining consent where organizations provide the choice to decline consent. Businesses use this method of obtaining consent because they recognize that customers do not take the time to read the end-user agreements before signing up.
