Stepchildren, second marriages and clear intentions
Blended families need clearer documentation than most. The default legal rules do not recognise stepchildren as heirs, and inheritance disputes between first-marriage and second-marriage children are sadly common.
What to think about now
The starting point is to write down, for yourself, who you actually want to inherit and in what proportions. Only then can a will be drafted to deliver that outcome.
- Decide how you want to provide for a current spouse and for biological children from a previous relationship.
- Decide whether you intend to provide for stepchildren you have raised.
- Look at any prior maintenance orders, divorce settlements or antenuptial contracts that constrain your choices.
- Consider whether a testamentary trust would protect a younger spouse's lifelong income while preserving capital for children.
Documents and decisions that matter most
Blended families benefit from clarity. Spell things out rather than relying on assumptions.
- A will that names every intended heir explicitly, including stepchildren if you wish to include them.
- If a spouse is to enjoy the home for life, consider a usufruct or a life interest with the property eventually passing to children.
- Update beneficiary nominations on retirement funds and life policies in line with the will.
- Keep a clean copy of the antenuptial contract on file - many disputes turn on what regime applied.
- If there is a family business, document buy-sell arrangements and how they interact with the estate.
Conversations to have
Silence is the enemy of blended families. The point of these conversations is not to seek permission - it is to remove surprise.
- Tell your spouse, in broad terms, what your will provides for them.
- If first-marriage children expect to inherit a particular family asset, say so or explain why not.
- Discuss stepchildren explicitly - silence often causes more hurt than the actual decision.
- Agree with your spouse what would happen to the family home if the second-to-die's estate is then distributed.
Common South African pitfalls
These pitfalls cause most of the inheritance disputes we hear about in blended families.
- Mirror wills that leave everything to the surviving spouse - and then the survivor changes the will and disinherits the children of the first to die.
- Forgetting that stepchildren do not automatically inherit; they must be named.
- Property held jointly, where the survivor takes everything by survivorship, was not intended to bypass children of the first marriage.
- Beneficiary nominations on retirement funds that still name an ex-spouse.
- Treating an antenuptial contract as just a wedding-day formality, when it materially shapes the estate.
