Getting married – does it affect a previously made will?

Marriage in Australia generally cancels a will, subject to some exceptions

Marriage and getting married is an important life event.  There is a lot to organise in addition to making arrangements for the wedding ceremony itself.

However, if research on will making in Australia is any guide, the making or updating of existing written instructions as to what is to happen on death following changed personal circumstances probably won’t feature highly on the list of things to do.

Yet attending to making a valid will taking into account changed or soon to be changed circumstances is important.  If not, the rules of intestacy would apply on death, and these may not produce the desired outcome.


Marriage generally revokes (cancels) an existing will

Wills and succession legislation in the Australian States and Territories contain provisions which revoke any existing will of a person when they marry.  It makes no difference what a person may have written in their will.

This general legal rule cancels any prior will upon the will maker’s nuptials.  However, there are exceptions and these can vary in extent from one state to another.

What the legislation says

Specific wills and succession legislative sections include:

Must be a valid marriage

For a marriage to cancel a previously made will, it must be valid in accordance with the law, see the Marriage Act 1961 (Cth) which applies to all states and territories. 

Section 88D of the Marriage Act 1961 contains provisions on the validity of marriages; the circumstances, consents, age, when and where solemnised.

Civil partnerships

In Queensland and the ACT, entering into a civil partnership, and/or a civil union (ACT), as defined in those jurisdictions also has the effect of revoking a pre-existing will.  Similarly in Tasmania entering into a registered Deed of Relationship revokes the terms of a prior will.  Again, similar exceptions can apply to these relationships as for marriage but the situation varies among the jurisdictions.

The exceptions

As mentioned above respective state laws provide exceptions to the cancelling effect of marriage on an existing will or parts of it, depending on the circumstances. It is important to note that these exceptions vary across the states and territories.  Exceptions generally concern:

  1.  Wills made in contemplation of marriage are not revoked if the union contemplated takes place. Some states provide that a will expressed to be made in contemplation of marriage generally, is not revoked by marriage.
  2. Under Western Australian law, a will is void if the marriage doesn’t happen, although this can be over-ridden if the will maker expressed a different intention. However in SA and the ACT, there seems to be a strict requirement in the law that the contemplation of marriage be expressly stated in the will, and that it does not extend as it may do in other states, to contemplation of marriage generally.
  3. A will in which the appointment of the spouse as executor, trustee or guardian won’t be revoked by marriage, if the will maker was married to them at the time of death.
  4. A will won’t be revoked if it makes a disposition to the person married to the will maker when they died.
  5. Wills made in the exercise of a power of appointment under certain conditions in particular situations, won’t be revoked by the marriage of a will maker.

Minors making a will

Under Australian succession law any will made by a minor (under 18s) is usually invalid.  However, there is an exception where minors may make a will in contemplation of a particular marriage to a named person, and this should not invalidate the will provided that the wedding takes place.  If the nuptials are not solemnised, the will is of no effect.

Since marital union affects the legality of existing wills through the operation of law and independent of the will maker’s intention, it is important to make a new will.  Circumstances vary and with the different exceptions, legal advice from a solicitor should be obtained.
