In most cases yes, a guarantor is an individual, often a close relative, who undertakes to assume the financial liabilities of the tenant including paying the rent in the event that they fail to do so. Where a guarantor enters into an agreement he or she normally agrees to meet the full obligations under the tenancy agreement on the tenant's behalf. This may include rent arrears, damage to the property, or other liabilities and obligations arising from the tenant's failure to comply with the lease covenants.
