Land mortgaging is one of the prevalent means of property related transactions in the country of Portugal. The country is said to possess very stringent laws when it comes to ruling real estate ventures and are often considered to be quite discouraging to and for investors. In case of mortgages or land leasing, there are two important parties who are involved. They are the land owners and the tenants. While it is usually noticed that in most cases, the land owners dominate the deals by deciding the terms and conditions of the contract, in Portugal the presence of the estate agents help to maintain equilibrium between the two.

The landlords and the tenants are two parties involved in case of property transactions. In such cases, the Portuguese constitution contains well defined laws which govern such activities. Like the land owners, the tenants who occupy the lands also have to conform to certain rules and regulations. There are certain specific periods in accordance with which the tenant can issue notifications to the land owners regarding the non-renewal of contract. These time periods vary accordingly. For a contract of over six years duration the notice period is for six months, between one and six years it is sixty days. The time period is for thirty days in case of contracts between three months to one year. For those agreements which specify less than three months, the notice period can be calculated as one third part of that duration. In case of age old properties, the tenants can claim that the land owners make the necessary restoration. In failing to do so, the tenant can occupy the property as its rightful owners on condition that they will carry on the repairs. If they are unable to do so, the property will again be returned to the original land owner.
