The Registration Act, 1908, the Transfer of Property Act, 1882 and the Real Estate (Regulation and Development) Act, 2016 mandates the registration of an agreement for sale of an immovable property. By registering the agreement for sale of an immovable property, it becomes a permanent public record. Further, a person is considered as the legal owner of an immovable property only after he gets such property registered in his name.

1. Title Deed (Escritura)
This document is essential, as it proves that you are the legal owner of the property. It must be registered in the Public Property Registry, and it is necessary to provide a certified copy to the buyer so that they can verify ownership.

2. Certificate of Freedom from Liens
This certificate, issued by the Public Property Registry, confirms that the property is free of mortgages, liens or other liens that may affect the sale. It is crucial to assure the buyer that there are no outstanding debts on the property.

3. Official Identification
You must provide a valid official identification (such as a passport or voter ID). In case the property is in the name of a legal entity, the articles of incorporation and the identification of the legal representative will be necessary.

4. Proof of Tax Payment
Property Tax: It is important to present the receipt for payment of the property tax up to date. This ensures that there are no tax debts associated with the property.
Income Tax (ISR) for the Transfer of Real Estate: In some cases, the calculation and payment of this tax must be submitted, although in many transactions, the notary will retain and pay this tax on your behalf.

5. Certificate of No Debt for Water and Public Services
This certificate shows that you have no outstanding debts with the company that supplies water or any other municipal service related to the property. It is important to ensure that the buyer does not inherit these debts.

6. Cadastral Plan
The cadastral plan is a document that details the dimensions and exact location of the property within the municipality. It is used to verify that the description of the property in the deed matches the physical reality of the property.

7. Utility Bills
It is advisable to have the latest utility bills on hand, such as electricity, gas, and maintenance (if applicable). Although they are not always mandatory, they can be requested to verify that there are no debts for these services.

8. Authorizations or Consents
If the property is part of a condominium property regime, you may need to present a certificate of no debt on maintenance fees and, in some cases, an authorization from the condominium administrator to sell the property.

9. Cadastral Certificate or Certificate
This document, issued by the local cadastral office, contains relevant information about the property, such as its cadastral value, surface area, and boundaries. It is important to ensure that the data in the deed is up to date.

10. Purchase and Sale Contract
Finally, you will need the purchase and sale contract, which is the document that establishes the terms and conditions of the sale. This document must be drafted and signed by both parties, and is usually notarized by a public notary.

11. Deed Permit
In some cases, a permit or authorization is required to sell, especially if the property is located in certain areas or is considered historical heritage.

Capital Tax (also known as Wealth Tax or Property Tax in some places) is a tax levied on the value of certain assets, such as real estate or high-value property. Eligibility for exemptions from this tax varies by jurisdiction, as tax laws and regulations can differ from country to country. However, in general terms, here’s how you might qualify for exemptions on Capital Tax:

1. Exemptions by Type of Property or Use
Main Residence: In many places, the owner’s main residence may be fully or partially exempt from Capital Tax. You should check whether your property qualifies as a main residence and meet the requirements set forth, such as living in the property for a certain amount of time each year.
Properties of Historical or Cultural Interest: Some jurisdictions offer exemptions for properties listed as historical or cultural heritage. If your property has this classification, you might qualify for an exemption.

2. Exemptions Based on Value or Amount
Exempt Value: Some countries have a value threshold below which the Capital Tax does not apply. If the value of your property is below this threshold, you may be exempt from the tax.
Low Value Properties: There are exemptions or reductions for properties that are considered to be of low economic value. It is important to know the specific limits set in your jurisdiction.

3. Exemptions Based on Use or Purpose
Agricultural Properties: In certain places, properties used for agricultural purposes may be exempt from the tax or receive a significant reduction. This is because these properties are considered to contribute to the food supply and rural development.
Social or Community Properties: Properties that are used for community purposes, such as health centers, education, or non-profit organizations, can often qualify for exemptions.

4. Local Tax Benefit Programs
Tax Incentive Programs: In some places, there are tax incentive programs that offer exemptions or reductions in Capital Tax for certain types of properties or for owners who meet specific requirements, such as low-income individuals or retirees.
Tax Credits: Sometimes, tax credits can be applied that reduce the amount of tax owed. These credits may be available for particular situations such as energy efficiency improvements to the property.

5. Ownership Exemptions
Elderly or Disabled Persons: Some jurisdictions offer tax exemptions or reductions for people over a certain age or people with disabilities. The specific criteria for these exemptions vary by local law.

6. Specific Procedures and Requirements
Required Documentation: You must submit documentation to support your exemption request, such as proof of residency, certificates of property value, or proof of specific use.
Apply Formally: In most cases, you will need to submit a formal application to obtain the exemption. This may involve completing specific forms and providing additional documentation.
Steps to Qualify for Exemptions
Research Local Laws: Review local or national tax laws related to the Capital Tax to understand what exemptions are available and what the requirements are to qualify.
Consult with an Expert: Speak with an accountant, tax advisor, or tax attorney for advice on your eligibility and the steps to take.
Prepare the Necessary Documentation: Gather and prepare all the documentation required to apply for the exemption, making sure you meet all the established requirements.

Submit the Application: Complete and submit the exemption application to the appropriate tax authority, following the established procedures.

Tax exemptions can offer significant relief from your tax burden, but it is essential to fully understand the rules and make sure you meet all the requirements to qualify.
