Talk to your partner
If you are considering a same-sex partnership or domestic relationship, you may be able to better understand each other's needs and aspirations by talking through the desirability of putting in place the various documents referred to above.
You should certainly discuss matters in some detail as soon as you agree to co-habit or intermingle your finances or jointly acquire property. Where one partner is substantially financially "better off" than the other it may be that a formula can be put in place whereby, over time, the less well-off partner effectively acquires an interest in the home and property you both mutually enjoy.
In some jurisdictions, the transfer of real estate from one same-sex partner to both partners jointly (or vice versa), may attract government "stamp duty" or transfer charges. De facto heterosexual partners and married persons usually enjoy an exemption from such imposts.
Be aware that discussion of these matters often bring questions of "trust" to the surface.
As already suggested above, it is not so much a matter of trust but rather of "protection" for both of you. If one or other of you were to be seriously incapacitated or even die, then that person's family members may be able to intrude into your lives and make it very difficult for the survivor at a difficult and emotional time.
In the event of a partner's death and without appropriate protection, the deceased partner's family may even be able to take over the home and exclude the surviving partner even after many years living together.
Partnership, Living or Co-ownership, Cohabitation Agreement/s
These documents may be separate or combined and are formal agreements between you both to regulate day-to-day arrangements and other matters, to record respective interests including contributions and apportionment and to define certain arrangements or requirements should a variety of circumstances arise.
The actual contents may vary widely from very basic provisions concerning some property or a financial arrangement, to extensive and complex arrangements seeking to regulate the relationship in considerable detail.
In some jurisdictions, the Court may require strict formalites to be observed if a binding financial agreement is to be effective. See for example: LAWS - AUSTRALIA - FEDERAL - PROPERTY.
Your friendly lawyer should be able to draw your attention to various considerations.
A questionnaire addressing many of the considerations that may be taken into account in the preparation of such agreements may be found here
. This document may aid you in preparing to discuss such an agreement with your partner and your lawyer.
Your Wills
See: Incapacity, Wills, Death and Inheritance
The death of a loved partner is traumatic enough without the survivor having added stress of the deceased partner's wishes not being legally recognised.
For example, without a valid Will, if the home is in the name of one partner only or where you are registered as tenants-in-common, the interest of the deceased partner may pass to a relative of that partner according to a pre-determined scheme for inheritance.
The law has changed in many jurisdictions and recognition of same-sex partners for the purpose of inheritance is now more commonly recognised.
See: Laws - Country - County/Province/Region/State - Inheritance
Powers of Attorney
These documents may be drawn up to give the power to your partner (or your partner jointly with someone else, or another person of your choosing), to act as if they were you in various circumstances.
The above documents may be known by different names in different jurisdictions, e.g. "Durable Powers of Attorney", "Health Care Proxies" and "Living Wills".
Statutory Declaration
In the absence of a statutory "domestic partners" registration scheme, a Statutory Declaration may go some way in proving that a same-sex relationship or domestic partnership is or has been in existence.
The law in a particular jurisdiction may require such a statutory declaration to comply with a certain, laid-down form.
Such a statutory declaration made by both partners at the time of commencing the relationship will at least provide some admissable proof of your relationship.
See: Declared Relationships Statutory Declaration for an Australian example.
You should have all these documents prepared by your lawyer, as certain formalities must be observed if the documents are to be legally effective and to avoid inconsistencies between these and other documents..
Keep Records
As a number of these arrangements are essentially based on "contract law", it is important to keep good records, especially with regard to property that you and your partner either acquire in your own names or jointly.
The Partnership, Living, Co-ownership or Cohabitation Agreement/s may include terms as to retention of property acquired in your name alone and jointly acquired property.
If you already own or are planning to purchase a home or any real estate registered in your name or jointly with your partner, you should maintain detailed records of your respective contributions to the acquisition, any loans entered into, and renovation or maintenance and repair expenses relating to the property.
It may even be very useful to maintain a chronological (in date order) narrative of the history of your partnership, noting all major events of significance.
