Cassie Newnham (pictured) insisted on a prenup before tying the knot with boyfriend of four years Brendon . Wedding dresses and venues might top the list of internet searches for most brides-to-be, but not for Cassie Newnham. When her boyfriend of four years popped the question, the 33-year-old wasted no time Googling prenuptial agreements instead. Despite being head over heels in love with Brendon, 38,  Cassie, who lives in London and is originally from South Africa, had spent years working hard to save for her future. And as her heart raced with wedding plans, her head told her to protect her assets. 'People think of a prenup as something you put in place in case you get divorced but it's actually a great way to safeguard your assets,' account manager Cassie said. She got engaged to Brendon in February 2013, when he went down on one knee during a trip to Cape Town for a friend's wedding. She continued: 'If you take life insurance out you're not protecting yourself from death, you're just insuring yourself in case.' Like Beyonce and Nicole Kidman – who are both reported to have prenuptial agreements – getting her man to sign on the dotted line before walking up the aisle was non-negotiable for Cassie. She thinks Cheryl Fernandez-Versini was wrong for not instigating one before her whirlwind wedding to Jean-Bernard Fernandez-Versini in July 2014. 'You always think "it will never happen to me" but you just don't know,' Cassie said. She continued: 'Quite a lot of our friends have prenups in place. If you've put money into property or built up your own career or company, that's something you should safeguard.' Cassie and Brendon's prenup was signed a month before their wedding day in Cape Town in January 2014 (Pictured: The couple at their wedding) If the Brendon and Cassie (pictured) split up each will keep all of the assets they acquired before their marriage took place . So as Cassie and Brendon planned their big white wedding in front of 98 guests in Cape Town in January 2014, they were also busy negotiating how they would split their future possessions. 'We both always thought prenuptial agreements were a good idea, so we were both in agreement we should get one done, says Cassie, who is expecting the couple's first child at the end of March. She continued: 'Neither of us felt awkward about it at all.' 'As well as the house we bought together before we got married, I have a property in South Africa left to me by my dad, and Brendon already had a property too. 'In addition, we both had savings.' Beyonce (left) has been reported saying a prenup is 'smart', Catherine Zeta-Jones (centre) is said to have one and Cheryl Fernandez-Versini (right) reportedly refused to sign one before her marriage to Jean-Bernard . The couple used online law firm Rocket Lawyer to draw up an official agreement and Cassie thinks more brides-to-be should consider doing the same. A prenup is a legally binding contract entered into before marriage . It protects people from losing money and assets . It commonly includes provisions for divisions or property or spousal support in the event of divorce . A prenuptial agreement isn't legally binding in the UK but will be taken into account during a divorce hearing . It is also possible to have a postnuptial agreement after the marriage ceremony has taken place. She said: 'You can tailor your prenup to whatever you want it to be, and it also protects you from debt. 'People think it's a legal agreement and you need a lawyer but it's really simple and cheap. 'We entered our details, declared what our savings and assets are and it gets checked by a lawyer. 'It cost us £25 and took about 20 minutes.' In the event of divorce, Cassie and Brendon have agreed to split all the earnings accumulated during their marriage by 50 per cent. The earnings accumulated before are their own. 'Prenuptial agreements are becoming more and more common these days – it's like taking out insurance. 'It hasn't impacted our relationship and we don't talk about it anymore. 'It's a good thing to have in place.' Keith Urban will allegedly receive $640,000 (£429k) for every year he is married to Nicole Kidman if they split . Beyonce and Jay-Z: Beyonce reportedly gets $5m (£3,349,634) with each child she bears and would receive $1m (£669,926) for every year the pair were married if they divorce. Nicole Kidman and Keith Urban: Keith will allegedly receive $640,000 (£428,753) for every year the couple is married – unless he uses drugs . Catherine Zeta-Jones and Michael Douglas: It's reported that if the Hollywood couple split she will receive $2.8m (£1,875,669) for every year of the marriage, and if he cheats on her she gets a $5m 'bonus'.
